ENGINE-STARTER Specification of Letters Patent.`

Applicationled February G. 1907. Serial N0`356|019i Patented Nov. 12, 19o?.-

To all whom 'it may concern.'

Be it known that I FRANCIS LENARD'ORR, a citizen of the United States, and a resident of ThurmanL in the county o Fremont and State of Iowa, have invented a .new and Improved Engine-Starter, of whichthe following is a specification.

The invention relates to means for starting gas or gasolene engines, and has for its object the provision of novel and improved power means adapted `for cranking internal combustion engines in general, stationary or mobile, but moreespecially for starting engines of the general character stated, employed on gasolene automobil/es. l l

The invention consists of a peculiar form of combined pump and engine vadapted for operative connection with the power shaft of the driving orpropelling engine, or other rotatable shaft forming apart of the driving or propelling engine, a tank with tubing providing cornmunicating passageways leading therefrom into the cylinder of the combined pump and engine, check and controller valves v in' the" tubing, and automatically openingreed and exhaust Valveson the combined pump and engine, the latter being oscillatory in character.

\Th`e invention may be more definitely stated as re sid ing in the specialconstriiction and arrangement of panas hereinafter fully described, and with thel novelty thereof pointed out in the claims.

In the Yfollowing detail description, reference is had to the accompanying drawing illustrating my invention in preferred form, the drawing being shown part in sec- In the practice o f my invention I employ a cylinder A, having oscillatory attachment at one'end, by means of a suitable bearing B, having support on a xedly lo- 'ing engine, on the power shaft II, of which, I arrange a crank-arm I.

`It intended that the crank-arm I shall be loosely erence characters J, K..

The projecting end L of the piston VE is suitably con'-k nected with the outer or freev end of the crank-arm I, substantially as shown by 'the figure of illustration.

M, N', indicate respectively, passageways, on opposite sides of the engine cylinder, having their ends providing open comm unica-tion into the cylinder, at opposite ends thereof, as illustrated` The passageways M, N, are provided respectively Vwith branch passageways O', 'P, and at the juncture oi 55 the passageways M, O, and N," P, I locate valves Q, R, `adapted toshift open communication of the passage- Ways into the engine cylinder, at opposite sides of its piston D, through operation of means illustrated in its preferred form, and which may be described as follows.

In constructing the valve operating means just re-' ferred to, I employ a bar YS and provide it with substantially central support, on a fixedly located journal, rod or shaft'T, having support onthe engine base, or other suitable location adapting its being held against move- 65 nient.

U, V, 7indicate links respectively lconnecting opposite ends of the bar S, with projecting ends ofthe respective valves Q, R. The valves Q, R, are constructed with angularly disposed openings W therethrough, shown by At the ends of the cylinder A, I arrange suitable inlet' ports A v, B provided with check valves C, held yieldingly seated by springs D.

My invention further comprehends the use of a storage tank E having a nipple or opening F, leading thereinto. At the outer end of the tank opening F I locate a two-way unioh or L-shaped pasageway GA v In one :passageway o f the union G I locate an automatic,

or puppet check valve H-, adapted to seat closing passageway leading through the union and into the tank E, and in the other passageway of the union Gf, I locate a valve I, held yieldingly seated, closing passageway through the union G, leading from the tank E. The

-valve I is provided with a proj ectingstem J', whereby, '85

through manual manipulation, the valve I may be vforced from its seat, thus opening up free passageway through the valve-casing.

K indicates a ileirlible tube, having one end suitably connected with the casing of the valve I and its other end extended to and affording communication leading into one end of a tube L the other end of the tube L being suitably connected with the bran-ch passageway P,',on the cylinder A.

M indicates a 'exible tube from the check-valve H into`one`end of a tube N, the other end of the tube N being attached to the cylinder nipple `or passageway O. In the passageway formed by the-'tubes M, N, I

locate an. exterior exhaust valve O, and provide it with an operating handle P, whereby the angularly disposed passageway Q through the valvelrnay be l adjusted from its illustrated position v completing open passageway from the cylinder A into the storage tank E', to cutting off communication leading from the cyl- 105 inder A into the storage tank E', and establishing providing passageway 95 l Ivalve I, by simple pressure on its stem J', .thereby permitting pressure o airto flow from-the tank E into justedto feedinto one or the other ends of thel cylinder premise by saying that under ordinary operation ofthe driving or propelling engine G, the crank arm is de-. 4 signed to hang loosely on the engine shaftsH, by obvious To effect starting up of the driving o r propelling engine strokeof the piston just described obviously the crank left, indicated'by the` arrow marked IThe bar S `the swinging movement' referred to, the valve. R will free exhaust from one or theother ends of the cylinder A, leading through the passageways M, tubes N, M and to the outer air, through the valve opening The constructionoi my improved engine starter will be understood from the above description.

Y In describing the operation oi invention, I would adjustment of the clutch device J, K, hereinbeiore d briefly referred to.' N'ow we will assume that thewtank is stored with suitable pressure of ai, and it is desired to boost or crank the engine G to start-it in operation.

as stated, it becomes necessary simply `to unseat the .one or the'other ends of the cylinder A. In thegure' of illustration the v'cylinder A is shown near the end of its oscillation with the piston moving downwardly, .and the valve R adjusted to ieed the compressed air into thefupperjend of the cylinder; A1, above its piston and operatingthereon with pressure designed to force the piston to completed down: stroke. During the down arm -I will be imparted turning'action, indicated by .the arrow thereonthrough connection therewith `of the piston rod E,andthe crank'arm being-fixedly secured -to therenginefshaft H, Abys'utable adjustment of' the Clutch device 1 K, itis apparent the engine shaftHA will be turned=thereby- During the action oi partsv justvdescribed itis further apparentthe freeor upper end-ofthe cylinder` A will be caused toswingto ythe vbeing hheld against endwise movement, -a's above def scribed, obviously when-.the cylinder'A has. completed be adjusted through connection of link V with the bars', t position, providing passageway-for fiow oi f compressed -air from the 'tank E@ into the cylinder A, tothe under side of the piston D. v Air pressure ybeing fed into the cylinder, under its piston as stated, the vpiston will be forced upwardly toward the otherend ofthe 'cylinder A, and by .such operative movement, effectcontinued rotary movement ofthe engine'shaft H. f

It will be noticed that connection of the valves R, Q, with the ,b'ar'S is-such, thatwhen the former is ad- A, the latterfvalve Q, is adjusted cutting off exhaust from thefeed end of the cylinder, and the other lend of the cylinder'opened up adapted for 'free exhaust in advance of the piston D, the exhaust passageway leading through the tube N', M', the valve O, and the outlet R from the valve O Y It will be understood that during the operation 'of parts above described', in boosting or cranking' the driving or propelling engine aboveldescribed, the: valve O is adjusted to position with its opening Q completing passageway through the cylinder end ofthe tube M', and the valve outlet R to the outer air. Now so 'long as theA valve l is held pressed down7 permitting flow of compressed air into the cylinder A, the piston D be made to` travel from end to end of the cylinder svoso A, and through its connection with the power shaft H, effect continued boosting or cranking of the shaft H, until the driving or propelling engine is effectively started up' and set running under its own power. Durin'g boosting or cranking of the engine shaft H, it is apparent thatlthe cylinder A will be imparted oscilla; tory movement, and that through the linked connection of the valves Q, R, with the bar S, the latter being held against lateral '.rnovement,` the valves Q, R, will be adjusted, the former permitting feed of air into the cylinder-A, and the latter permitting exhaust of air from the cylinder A, in advance of its piston D. When the driving'or propelling'engine is effectively started in operation, pressure is removed-.from the valve stem J Atthe same time .the valve l in feed passageway leading from the tan E into the cyl-ndgrli, will be forced. to its seat or closing adjustment. 4In vthe gure of illustration, all the valves are shpwn in position with the piston forcing air, drawn into the-cylinder through itscheck valve openings A', B. Now it being assumed that-the driving or propellingl engine has been given .operative boosting or cranking action, with all the valves in theconveying passageways adjusted as illustrated; working operation of the driving or propelling engine will leffect restoring of'air` into the tank E',

4thereby maintaining required .air pressure therein,

which air pressure may -be ascertained by an indicating 'device on the storage tank.

' It will be apparent fromthe above description that my invention involves means, in oneapparatus orde:

vice, serving as an engine to crank the power shaft'igf the driving or propelling engine, whereby' to start it in operation, .through force of stored up air, and at the same time is adapted for operation as a pump whereby .to restore pressure of air, thus at all times insuring adequate motive power in the storage tank for effective 'recranking or starting ofthe driving or propelling en-v gine, as occasion-may require.-
